He wrote: "With our deepest condolences and with our thoughts and prayers to all those affected."

A member of the LGBT Foundation has spoken out about the interview to The Telegraph.

"What it shows is why it's important - because there has not been that many times when the LGBT community has been mentioned or highlighted by the royal family - with it being a younger heir to the throne who is understanding of diverse communities.

"The fact that he has agreed to be in Attitude and signing books of condolences for the Orlando massacre, shows the importance of reaching out to the LGBT community.

"I'm really looking forward to seeing how he appears - this will be warmly welcomed."
